The system accommodates these passengers by letting them fill seats on Air Force air transport flights that would otherwise be left empty. The seats are made available on a space-available basis. Unused seats on DoD-owned or controlled aircraft are made available once all the space-required (duty) passengers and cargo have been accommodated. Much more info motion about Space-A is provided here. Dependents of deployed Military Members are eligible to fly Space-A if the member has been deployed for more than 120 consecutive days ... see DoD memorandum.
